My friend is becoming really thin and ill recently, but i don't know what to do to help. i think she might be anorexic?

Anorexia Nervosa: Anorexic are obssessed with how many calories... Fearful of eating.. Workout a lot and always weigh themselves. They are perfectionists and successful and they a lot more women than men. Depression mostly tired with low energy poor appetite with no interest and do not like to socialize or befriended with others. Do not even the energy to work out... Take her to doctor to check out everythin els.
